Anothenobjeot of the invention, ie to pro Vide Ineans vp1' ,eral'ily assoeiated withlk the above 'imentioned-v sli-eel'{onli-ling-l deyioes, to

flatten' the completed product as'it proceeds Y movable strands are necessarily `shifted vfor a considerable distance-relatively to the central strands, and during each such shiftingV movement to one side or the other of the central strands it is desirable to provide meansJ of an unusual characterl to compensate for the momentary increases in the length of the movable strands relatively to the central strands, and also means to keep the movable strands under constant tensionlduring each of their shifting movements toward the central strands.'Y For this purpose l have deviseda novel compensating` device'whicli will be described at length hereinafter.

Other objects of this invention comprise improved means for controlling the tension of the warp strands as delivered to the machine, adapted to permit the provision vof electrically operated devices tofstop the -operation of the machine in the event of eX- haustion, breakage, entanglement or other interference with the regular supply of any one or more ofthe warp strands, or of the filling; also improved means for drawing off the completed product; and the object and result of these improvements, individually and in conjunction with each other, and with those already recited, and others which will be made to appear hereinafter, is to provide a process of Weaving capable of greatly increased rapidity of action in the loom carrying it into effect, in comparison with certain other processes for performing analogous operations; also to provide for carrying the process into effect by a machine of simpler construction and operation, with greater output, than machines which employ a. reciprocating shuttle in the formation of flat wire tape and similar products.

Another object of the invent-ion is to so organize the weaving sheds in an upright position, with the circular path traversed by the shuttle in such close proximity to the central warps, that the mass of'iilling supply carried by the shuttle will develop a minimum centrifugal and gravitational moment, with the notable result that a large quantity of filling can be utilized without undue strain upon the mechanism, and thus the important advantage is secured thatrv the large filling supply permits a long non-stop run of the machine, with greater economy in production and fewer piecings of the weft.

. In the illustrated vembodiment is vshown a loom comprising a pedestal'l, the upper' portion 2 of which constitutes the base for a head3 in and on which are 'mounted the principal operating parts of the weaving mechanism ofthe loom, to be described later in detail.

In, accordance withV the invention, provision is made for supporting a group ofwarp strands w1 in a central position, occupying a plane transversely of the mach-ine, and of superimposed segmental plates 4 6, 47 and 48 arranged in stacks spaced apart to form the transverse diametrical path s1 within which the movable group Vof warp strands w is shifted from side to side, this path being eX- tended by the notches szrand s? :in the ring-` The ring-plate 42rests upon shoulders on the studs V57 and is thus supported at the proper height. i

The ring surface 44 of the member 37, and the opposed periphery 45 of segments46 form the race'way s for the shuttle slipper 32; the similar surfaces 44 upon the upperring-plates 42 and 43 and the opposed surfaces 45con Jthe segments 47 and 48 perform the like office for slippers 33 and 35; while the plate 34 of the shuttle extends outwardly between ringplates 42 and 43, serving to steady the shuttle at all points in its path, but more particularly to bridge the gaps where the transverse warp path s1 intersects the circular shuttle path s. The plate 34 acts also asa spreader to keep the warp strands 'w from fouling the teeth of .the rack 3l. v

The ring-plate 43- is `held above the ringplate 42 at the proper height to permit free revolution therebetween of the shuttle plate 34, this position of the ring-plate being maintained by the spacers 56 surrounding the trunnions 57 of intermediate gears 58 which serve to connect the driving gears 40 properly for rotation in unison to actuate the shuttle by engagement with its rack 3l, which is at all times in mesh with one or more gears 40, even when crossing the 'gapsl 82 and 83. The gears 40 are arranged in two sets of four on each side of the weaving head, Vbeing necessarily separated bythe aforesaid gaps s? and ,83, so that the invention desirably provides means to drive the two sets of gears in synchronism.

VThe ,illustrated means for the above purpose comprises a shaft 59 driven byva gear 60 in l mesh with the gear 24 onthe'main shaft 27 and on the shaft 59 are spiral gears V61 engagedwith spiralgears 62 on short vertical counter-shafts 63 on each of which is mounted one of the driving gears 40.

As the shuttle S is thus caused to revolveV ber 812 carried by another post 311 extending from the shuttle headS, the members12 con# stituting a spreading device for the warps, and this spreader is pierced at S13 by an aperture through which the fillingstrand '1,02 is led to the eye s6 of the spindle in such a manner as to keep it from entanglement `with the warpsas the latter pass from the heddles at Vthe regions2 to the point 815 where the shed is completed and where the filling wz is -laid into the shed. f Y

The very stiff character ofthe wirercon- Vstituting the warp strands employed in the at s which may `desirably be a segment of a circleY as indicated in Fig. 8, wherebyeach Atime that the spindle occupies within the shed a position such as that shown in Figs, l and 2 it WillspreadV the warp Vstrandswin arcuate relation to each other and to the needle a5, avoiding any interference with free passage of the needle during the moment of laying the filling w? in the shed.

As a further improvement in pursuance of the above purpose, means-are provided to cause the shed to be opened to a slightly greater extent than would occur if the centrail warp strands w1 were allowedto remain in a truly vertical position, and accordingly provisionV is made to cause the central warp strands to swing slightly out of the vertical,

thus presenting the shed in a more favorable position to permit passage of the needle as it lays the filling in the shed. Preferably this lswinging movement is accomplished/by providing an oscillating closing or take-off member 815 in the form of a yoke through which the completed tape is led to thetake-up mechanismT, (see Fig. 2) and the member S15 is shown in Fig. Sas bolted adjustably at 171 to a pendulum S16 mounted pivotally at S17 upon4 the gallows head 7 0 of the over head portion ofthe frame, the pendulum l615 being fixed upon a rock shaft slsrfrom whichrextends a lever'sw'with a frictionV roller S20 engaged with f a cam 821 upona counter shaft S2?, the action of the cams21 being to causethe necessary oscillationY of the member S15 for thefpurpose above described. rlhe countershaft s2? is actuated by'bevel gears 823 and 824 (see Figs. 2 and 3)y the latter being fast upon a vertical shaft s25 mountedY in bearings 7l and 72 and having at its lower end a bevel gear 73 engaged anddriven by agbevel gear 74 upon a coimtershaft 75 which in turn has a lgear 7o driven by a chain 77 running to a gear 78 upon fas nez-aww een@ e1) f, mejeeeededj-ueeemy me; e weke laebbefrfceker 4yielding materie :en

00m/trolling mechanism Y Y Suitable mechanism is provided to control the operation of the machine, for which purpose I have shown a shipper handle 121 conveniently located, mounted pvotally at 128 (seeFigs. 2 and 3) upon a bracket 122 and connected by an adjustable link 124 with a lever 125 provided with a yoke 126entering a groove in the hub 127vof -the clutch member' k26 and operating in well-known fashion'to' throwthe clutch into action and out of action. When the clutch isthrown out of action the machine may be operated Vmanually by means of a hand-wheel 128 upon the shaft 59. Y Y Y Preferably provision is made for stopping the machine automatically in the event of any interruption of the regular delivery of the supplies of warp strands 'w and w1, and any suitable mechanism may be provided for this purpose, the supplies of wire being preferably introducedto the machine (see Fig. 1)v through a tension device 145 comprising sets of rolls 146, 147 and 148 mounted on asuitable standard 149V mounted on the foundation upon which the loom stands. The warps are shown inthe instance illustrated as derived from drifts or spools 150 of which there may be asmany as are required, and"` these aresupported conveniently upon any suitable creel 151. As one convenient form of mechanism to cooperate with the strand wires in providing proper tension and also in kaccomplishing stoppage of the loom automatically when desirable, the inventioncom- 'prises a series of pulleysl152, one foreach of the warp strands, each pulley beingprovided 'with a coil spring 153 secured upon the base yof the frame 149. Y Each warp strand is led around one of these pulleys, passing therefrom overl the direction rolls 147 and thence to the rolls 4 and 80, The rolls 147 are preferablyA acted upon by spring-controlled retarding devices 154, which cause the rolls 147 to exertY suflicient drag on the portions of the warps within the tension device 4to place the springs 153 under very slight tension. Iffor any reasonany strand wire is not delivered from the creel with desirable regularity, as for example if such a wire becomes kinkedor entangled in its drift or such a kink formsin a manner that prevents passage of the wire freely past its springcontrolled pulley 152, the tendency of such an obstructed wire will be to liftV `form of attachment for this In Figs. Sband 3 run freely beneath them, but which will be raised by the passage of a kink in the wire and are suitably connected to cause stoppage of the loom automatically, as for Vexample by means of electrical circuits, which are not shown, as these donot constitute anl essential part of my present invention, and inasmuch as the operation of such stop-motion devices is well understood' by those skilled in the art. c

Such detectors may also be'arranged to stop the loom upon breakage Vof. a warp, or exhaustion ofthe supply on'vany of the supply reels. Y

In Figs. 13, 14, and 15 is shown a part `of a wire tape produced by the machine illustrated, in carrying into effect the improved method of weaving herein disclosed, and in this form of the tape the warps 'w and w1 are laid in close order and the filling Iw2 occupies substantially a single plane, as' indicated in Figs. 14 and'15, the warp threads ,crossing the said plane in the weave, as illustratedin Fig. 14. This form may Vbe pro'- duced by the machine 'as set forth'in Fig.3.

In Figs. 11 and 12 is shown a form of tape in which the avarps lw and w'1 occupy a single plane and are separated by the thick-` ness of the filling wire lwg, which is bent around the warps as illustrated in Fig. 12.

purposes, as for example in a wire tape for YtireA beading, and vits production `constitutes ya novel and important objectof this invention. Any suitable means may be utilized to effect the desired bending of the wire w2 aroundthe warps lw and w1, and I-have deyvised an attachment for the loom already described which avails of the relative flexibility of the filling wire wz, as compared vwith the stiffer warps, to accomplish the bending just after the filling has been laid into Thisform of fabric is preferable for some Y the fabric, and Iwill describe a now preferred i purpose. I have shown a device adapted to operate uponthe wire tape VZ pro, ,'ressively as it passes from `the closing members?5 to the drawing-od drum 90, this deviceV comprising aset of rolls 163, 164, and

165, mounted upon a block 161 carried byV the pendulum 816 which carries theshed-closing member S15 and to which the block is fastened, as by a screwl 171. Y

One roll is preferably adjustable, and for this purpose the roll 165 'issecured by a- I Vscrew 166 upon a slide 167 mounted in ways v168 upon the block 161, and is held in adrigmrsets l 'fandtjhus 'the 'necessary amount of -`filling' to compensate for the bendinglmayjbe drawn* into place-(Without bending KlSWar'PS,2 the i ositiona-sthe weavinof roceeds 'sotlia't'the 5 b 7 mov-'able '-Warps :to 'and ffro between. the Warps f 'offsaidrcentralrgroup,randradvancing/said cen` f tral and :movable warps llengthwise .to ac- A'-'c'om'plish V@said continuous weaving.
